[Samsung NP350E5C-A02AU] machine does not wake up with lid open - suspend is disabled

[slumbergod]

Samsung NP350E5C-A02AU notebook

The problem below was NOT present in Ubuntu 13.04

In xubuntu power options, machine is configured not to go to suspend when laptop lid is closed.
Once or twice a day, upon opening the lid I am presented with a black screen and I am unable to wake the machine. The only solution is to force the laptop to shutdown by holding down the power button.

On the one occasion the machine did wake (random key presses) it was unusable...the mouse was so slow I was unable to use it to reboot the machine.

I have tried permanently disabling suspend and hibernate with hacks found on forums but nothing has worked.

slumbergod, thank you for reporting this and helping make Ubuntu better. The next step would be to fully commit bisect in order to identify the offending commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[slumbergod (slumbergod)]

Yes, will start testing now. When I find where the problem started I will post on my open bugs.

Update for the benefit of anyone else experiencing this problem.

Kernel v3.9-rc8-raring works - no suspend / wake-up issues (final Raring kernel released)

[slumbergod (slumbergod)]

Kernel v3.12-rc7-saucy works - no suspend / wake-up issues (final Saucy kernel released)

Now testing Trusty kernels

[slumbergod (slumbergod)]

Kernel v3.13.0-29-trusty FAILED - suspend / wake-up issue present

Now testing first Trusty kernels release

[slumbergod (slumbergod)]

As of 3.13.0-30-generic the bug seems to have been resolved

For future reference these are the ones I had tested. Curiously, the issue seemed to only happen with the "official" kernels in the repos up until 3.13.0-30
